After the cap'has been properly screwed down, thepiece '5 is moved to the position shown in full lines in Figs. 2 and 3, so that the bentends 6. engage the casing 2, thereby preventing the accidentalfloosening of the cap 3.' The piece 5 is preferably of some spring metal which will exert 'a' pressure upon the casingfiwhen in'its operative position. The piece5 may he moved "rnEXiBLn JOINT.
